SR20DET
Origins
![](http://upload.wikimedia.org/wikipedia/commons/thumb/e/ed/Nissan_SR20DET_U13.jpg/250px-Nissan_SR20DET_U13.jpg)
The SR20DET was first produced in the U12 Nissan Bluebird 2000SSS Attesa in October 1989 [1]. From 1990 through to 1994 it was used in the Nissan Pulsar GTi-R (RNN14) however with a bigger T28 turbo. In both these cars the engine is aligned in a transverse fashion.
However the RWD Nissan Silvia produced from 1991 were built with a longitudinally aligned SR20DET.
The engine was used in the Nissan Avenir in 1995, the Nissan R'nessa in 1997 and the Nissan Liberty in 1999.
Out of all the Nissan models produced with the SR20DET, the Silvia was the longest running model to use it. The S14 and S15 use a bigger turbocharger than the S13 models.
